Woodward 9905-709  数字同步器和负载控制装置

【产品详情】

该装置是伍德沃德 DSLC 数字同步器和负载控制装置，部件号 9905-709。该器件是基于微处理器的控制，用于并联、同步、加载和卸载三相发电机组。它设计用于伍德沃德速度控制器和自动电压调节器（或其他兼容设备）。9905-709 型不具有功率因数控制或过程控制功能，因为它是伍德沃德系列中降级的升级级别型号之一。

9905-709 的一些功能包括：

内置诊断

通过手持式编程器终端实现设置、计量和诊断功能 

发电机自动装卸

压降、基本负载和同步负载控制功能

反向功率继电器。

9905-709 DSLC 的额定输入电压为 240 Vac，速度偏置为 1-5 Vdc。这款开放式 Delta PT 配置装置的额定工作温度为 –40 至 +70 °C（-40 至 158 F），存储温度为 –55 至 +105 °C（-67 至 221 F）。

9905-709 型提供相位匹配或滑差频率同步。两种方法的实际滑差频率和断路器延迟值用于预测两种方法在实际断路器闭合时发电机和母线之间的最小相位差。该控制器具有自动死总线闭合功能，其中只有一个 DSLC 控件通过通信网络上的锁定技术被授予死总线闭合权限。

在安装过程中可能启用或禁用的其他同步器功能包括：

延时自动多色重合闸

电压匹配

自动重新同步

同步器超时报警

【英文介绍】

The unit is a Woodward DSLC digital synchronizer and load control unit, part number 9905-709. The device is a microprocessor-based control for parallel, synchronous, loading and unloading three-phase generator sets. It is designed for use with Woodward speed controllers and automatic voltage regulators (or other compatible devices). The Model 9905-709 does not have power factor control or process control, as it is one of the downgraded-upgrade models in the Woodward series.

Some of the features of the 9905-709 include:

Built-in diagnosis

Setup, metering and diagnostic functions are achieved through a handheld programmer terminal

Generator automatic handling

Voltage drop, base load and synchronous load control functions

Reverse power relay.

The 9905-709 DSLC has a rated input voltage of 240 Vac and a speed bias of 1-5 Vdc. This open Delta PT configuration unit is rated for operating temperatures of -40 to +70 °C (-40 to 158 F) and storage temperatures of -55 to +105 °C (-67 to 221 F).

The model 9905-709 offers phase matching or slip frequency synchronization. The actual slip frequency and circuit breaker delay values of the two methods are used to predict the minimum phase difference between the generator and the bus when the actual circuit breaker is closed. The controller has automatic dead bus closure function, where only one DSLC control is granted dead bus closure permission through locking technology on the communication network.

Other synchronizer features that may be enabled or disabled during installation include:

Delay automatic multi-color reclosing

Voltage matching

Automatic resynchronization

Synchronizer timeout alarm
